Subject: [patch] vfio: fix a warning message
Date: Sat, 21 Nov 2015 13:32:21 +0300 [thread overview]
Message-ID: <20151121103221.GC7002@mwanda> (raw)
The first argument to the WARN() macro has to be a condition. I'm sort
of disappointed that this code doesn't generate a compiler warning. I
guess -Wformat-extra-args doesn't work in the kernel.
